A technicue has been developed to predict the noise generated by queues of vehicles accelerating directly across a controlled intersection. A pooled estimate of the correlation coefficient between measurement and prediction of 0.91 was obtained, indicating the validity of the method and its suitability for use in more general situations for non free-flowing traffic. Noise profiles and motion characteristics have been obtained for decelerating vehicles at a controlled intersection that can be used as a prediction method compatible with that for accelerating vehicles, to obtain the noise climate at an intersection. The effect of sampling rate on the statistical analysis of the noise received from an accelerating heavy vehicle has been studied using a computer simulation model, and results indicate that a sampling rate with a period of less than 1 second must be used, in order that the noise descriptors accurately represent the received noise climate.
